6. Verify output voltage accuracy for each of the voltages listed in the following table for your model
number. For each test point:

Select the correct source range.

Set the Series 2600B output voltage to the indicated value.

Verify that the multimeter reading is within the limits given in the table.

7. Repeat the procedure for negative output voltages with the same magnitudes as those listed in
the previous table, as applicable.
8. For the Model 2602B/2604B/2612B/2614B/2634B/2636B, repeat the procedure for the other
channel.

Voltage measurement accuracy

Follow the steps below to verify that the Series 2600B voltage measurement accuracy is within
specified limits. To perform this test, you will set the source voltage, as measured by a precision
digital multimeter, and then verify that the Series 2600B voltage readings are within required limits.
1. With the power off, connect the digital multimeter to the Series 2600B output terminals using
4-wire connections (use the same connections as in the figure titled "Connections for voltage
verification" in
2. Select the multimeter DC volts function.
3. Select the Model 2602B/2604B/2612B/2614B/2634B/2636B single-channel display mode.
4. Enable the Series 2600B 4-wire (remote sense) mode:
a. Press the CONFIG key and then the MEAS key.
b. Select V-MEAS > SENSE-MODE > 4-WIRE.
5. Set the Series 2600B SMU to both source and measure voltage by pressing the SRC and then
the MEAS keys.
